Milling Machine process at the cutting area: A diagrammatic representation
The process of cutting away material by inserting a workpiece past a rotating multiple tooth cutter is known as milling. The action of cutting by many teeth around the milling cutter leads to a fast method of machining. The machined surface takes various shapes like flat, angular, or curved,including any combination of shapes. The milling machine is the one which holds the workpiece, rotating the cutter, and feeding it.
Methods of milling
There are two methods of milling. They are as follows:
Up Milling: Also known as conventional milling, the cutter rotation's direction is opposite to that of the feed motion. For example, if the cutter rotates clockwise, in up milling, the workpiece is fed to the right.
Down Milling: This is also known as climb milling. Here, the cutter's direction is same as the feed motion. For example, if the cutter rotates counterclockwise ,in down milling, the workpiece is fed to the right.
Types of milling
There are different types of milling and accordingly different spindles are used. We describe some types of milling below:
Peripheral Milling
Also known as slab milling, in peripheral milling, the milled surface is generated by teeth. These teeth are located on the area of the cutter body. The axis of cutter rotation is usually in a plane which is parallel to the surface of the workpiece to be machined.
Face Milling
In this type of milling, the cutter is mounted on a spindle whose rotation axis is perpendicular to the workpiece surface. The milled surface is attained from the task of cutting edges located on the face and periphery of the cutter.
End Milling
In end milling, the cutter rotates on an axis vertical to the workpiece, which can also be tilted to machine tapered surfaces. Cutting teeth are fixed on both the end face of the cutter and inside the cutter body.
